Description DRV8825 stepper motor driver compatible, 4-axis Arduino CNC Shield v3. Features GRBL 0.9 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals) Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others) (Not Included) PWM Spindle and direction pins 4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins A4 and A3) 2 x End stops for each axis (6 in total) one Probe Coolant enable output Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping ) Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place. Runs on 12-36V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
